Checking The Blade-Stopping Time; Selecting A Blade - Toro Groundsmaster 4500-D Operator's Manual

Note:
The InfoCenter displays "traction denied"
and the machine should not move. If the
machine does move, there is a malfunction in
the interlock system. Correct this malfunction
before operating the machine.
Checking the
Blade-Stopping Time
Service Interval: Before each use or daily
Note:
Lower the cutting units onto a clean section of
turf or hard surface to avoid throwing dust and debris.
To verify this stopping time, have someone stand back
from the cutting units at least 6 m (20 ft) and watch the
blades on 1 of the cutting units. Disengage the PTO
and record the time it takes for the blades to come to
a complete stop. If this time is greater than 7 seconds,
adjust the braking valve. Call your authorized Toro
distributor for assistance in making this adjustment.

Selecting a Blade

Standard Combination Sail
This blade provides excellent lift and dispersion in
almost any condition. If you require more or less lift
and discharge velocity, consider a different blade.
Attributes: Excellent lift and dispersion in most
conditions.
Angled Sail
This blade generally performs best in lower heights of
cut—1.9 to 6.4 cm (3/4 to 2-1/2 inches).
Attributes:
•
Discharge remains more even at lower heights of
cut.
•
Discharge has less tendency to throw left and
thus leaves a cleaner look around bunkers and
fairways.
•
Lower power is required at lower heights and
dense turf.
High-Lift, Parallel Sail
The blade generally performs better in the higher
heights of cut—7 to 10 cm (2 to 4 inches).
Attributes:
•
It has more lift and a higher discharge velocity.
•
Sparse or limp turf is picked up significantly at
higher heights of cut.
•
Wet or sticky clippings are discharged more
efficiently, reducing congestion under the cutting
units.
•
It requires more horsepower to run.
•
It tends to discharge further left and can tend to
windrow at lower heights of cut.
DANGER
Using the high-lift blade with the mulching
baffle could cause the blade to break,
resulting in personal injury or death.
Do not use the high-lift blade with the baffle.
Atomic Blade
This blade was designed to provide excellent leaf
mulching.
Attributes: Excellent leaf mulching
